Notes:
At first were most of acanthites described as argentite. On the present
days argentite does not exist as single mineral species and
International Mineralogical Association (CNMNC IMA) one characterize as "hypothetical mineral (synthetic, anthropogenic,
etc.)". According to analytical data is argentite stable only at
the temperature
higher than 177 °C. That means cubic crystals of natural argentite are acanthites.
The names of acanthite (=argentite) in older German written literature
are Silberglanz and Glaserz. Silberschwärze is an old German name of
fine-grained black
aggregates of sulphides often with important content of acanthite.

Notes:
Oldest occurence of andorite described Cambel (1960) from locality Pod Babou
near
Pernek on the basis of optical research. Later research the same samples
shows that this mineral is bournonite (Cambel & Krištín, 1977). The
latest research this locality not prove presence of andorite (Luptáková, 2007).
